Abstract (en)

Workpiece support (1) for supporting a plate-shaped workpiece to be processed, comprises a number of elongated supporting elements (3), which support the workpiece in its supporting position, and a lowering device (4), by which the support elements are respectively moved from the supporting position to a lowering position, where the lowering device comprises: at least one elongated- and flexible transmission device (5), on which the support elements are coupled along its longitudinal extent, and which is deflected transversely to its longitudinal extension; and at least one deflection device. Workpiece support (1) for supporting a plate-shaped workpiece to be processed, comprises a number of elongated supporting elements (3), which support the workpiece in its supporting position, and a lowering device (4), by which the support elements are respectively moved from the supporting position to a lowering position, where the lowering device comprises: at least one elongated- and flexible transmission device (5), on which the support elements are coupled individually along its longitudinal extent, and which is deflected transversely to its longitudinal extension; and at least one deflection device, which is movable along the transmission device, for local deflection of the transmission device, where the local deflection of the transmission device with a movement of a support element or a group of adjacent support elements, which is/are coupled to the transmission device in the local deflection is/are associated in a lowered position, and the transmission device comprises a chain, a belt, a tape or a rope, preferably a bushing chain or a roller chain. An independent claim is also included for a workpiece processing machine, preferably a laser processing machine comprising a workpiece support for supporting the plate-shaped workpiece to be processed, and a working tool, preferably a laser processing head movable relative to the workpiece support.

Abstract (de)

Die Erfindung bezieht sich auf eine Werkstückauflage (1) zur Abstützung eines zu bearbeitenden, vorzugsweise plattenförmigen Werkstückes, mit mehreren, vorzugsweise länglichen Auflageelementen (3), die in ihrer Abstützposition das Werkstück abstützen, und mit einer Absenkeinrichtung (4), durch die Auflageelemente (3) jeweils aus der Abstützposition in eine abgesenkte Position bringbar sind, dadurch gekennzeichnet, dass die Absenkeinrichtung (4) mindestens ein längliches flexibles Übertragungsmittel (5) aufweist, an dem entlang seiner Längserstreckung die Auflageelemente (3) einzeln angekoppelt sind und das quer zu seiner Längserstreckung auslenkbar ist, und mindestens ein Auslenkmittel (6), das entlang des Übertragungsmittels (5) verfahrbar und dazu ausgebildet ist, um das Übertragungsmittel (5) lokal auszulenken, wobei eine lokale Auslenkung des Übertragungsmittels (5) mit einer Bewegung eines Auflageelements (3) oder einer Gruppe benachbarter Auflageelemente (3), das/die im Bereich der lokalen Auslenkung an das Übertragungsmittel (5) angekoppelt ist/sind, in eine abgesenkte Position einhergeht.
